The Earliest Reasonably Obtainable Map Showing The Discovery of America
Bernardus Sylvanus' pseudo-cordiform map of the modern world, published in Venice in 1511 is a map of landmark importance. The map is the second second atlas map of the World to show America, pre-dated only by the Johann Ruysch's map of 1507. It is also the earliest obtainable printed map to show and name the island of Japan.
Sylvanus' world map is one of the earliest obtainable maps of the world to include a portion of America, following the discovery of the New World by Columbus. Sylvanus's map is also the one of the earliest world maps printed in Venice and the first world map printed in two colors. A printing mistake in Asia, the duplication of the toponym "come" in both red and black, reveals that the color was added using separate registers.
In his dedication to Andreas Matheus Aquaevivus, Duke of Adria and Lord of Eboli, Sylvanus lamented that Ptolemy's charts were not reflective of modern sailors' experiences. Sylvanus constructed this world map as part of his attempt to reconcile and improve upon Ptolemy's version of the world, by integrating new information showingthe world as Europeans were coming to know it at the beginning of the 16th Century.
The land masses are vigorously engraved with mountain ranges, rivers, and place names. The map is surrounded by a dozen decorative windheads and three signs of the zodiac: Cancer and Capricorn for the tropics and the scales of Libra representing the equator. The sides of the map are embellished with information on the climates with seven climates (represented as windheads) recorded above the equator and 4 below. Latitude runs from eighty degrees north to forty degrees south, while longitude is 320 degrees wide, although his numbering of longitude reveals that he thought there was more global space than he chose to show in this map.
Sylvanus' map integrates a considerable amount of modern information. The British Isles, the Indian Peninsula, and Africa all reflect the work of modern cartographers. Scotland is situated north of England and Wales, not extending horizontally east as in Ptolemy's maps. There is no strip of land connecting the southern part of Africa with Asia, making Africa circumnavigable.
Asia is a mixture of old and new. There remains a large peninsula in Southeast Asia, a holdover of Ptolemy's Afro-Asian bridge that made the Indian Ocean an insular sea. However, the islands "Java Minor" and "Java Maior" are products of the dissemination of Marco Polo's travels, making the region a synthesis of ancient and more recent sources of information. Due to a scribal error, the island of "Java Minor" was substituted for Champa, leading sixteenth century mapmakers to locate the lesser Java over a thousand miles from "Java Maior." The latter became associated with Terra Australis and thought to be part of a huge southern continent.
Near the eastern border of the projection is the island of "Zampagv" (Japan), only the second printed map to include Japan and the first time it featured in an edition of Ptolemy's works. The first appearance is on the Contarini/Rosselli map of 1506 of which there is only one known copy. Sylvanus' "Zampagv" is similar in shape to an unnamed island included in the Ruysch world map of 1508. Ruysch himself does not label Japan and instead explains that he thinks it likely that the island of Hispaniola is Japan, but he left an unlabeled island just west of Hispaniola as an alternative. Sylvanus adopted the shape of the unnamed island as his Japan, but correctly moved it from the Caribbean to the Far East.
Although partial and somewhat speculative, what Sylvanus does include of the Americas is important, as it presents a fascinating view of the post-Columbian world. The name "Terra Sanctae Crucis" is used for South America, whose only label is of cannibals, "canibalis roman." This is most likely meant to be "canibalis comon", after a description in the Ruysch world map of 1508, or "canibaluz domon", domain of the cannibals. At the extreme south of the continent is an undefined coastline, perhaps a suggestion of a southern continent or island, which would reconcile part of Ptolemy's map-a southern land formed of the Afro-Asian land bridge-with this updated version of the world. Similarly, Sylvanus leaves the coasts unfinished in the Americas and the east coast of Asia, making way for the possibility that those continents might connect.
To the north is the island "terra laboratorus" and a region named "regalis domus", an inverted Latinization of "corte real" or royal court. Together, these lands are among the earliest appearances of the coast of northeastern North America on a printed map. "Terra laboratus" is attributed to the Portuguese-Azorean navigator Joao Fernandes, but Sylvanus' placement of the island suggests that the mapmaker thought that Fernandes had located Greenland, not an island farther west. "Regalis domus" represents the Portuguese explorations of Gaspar and Miguel Corte Real in 1501. The brothers made contact with indigenous peoples and Miguel transported a group of them back to Lisbon. However, Gaspar's ship disappeared and Miguel too vanished when he returned to look for his brother a year later. Most contemporary maps use "terra corte real" after the brothers, yet Sylvanus chose instead "regalis domus", which also translates to royal house. As Don McGuirk argues, this may have been because Sylvanus was aware that John Cabot, an honorary Venetian in the employ of the English Crown, had made similar discoveries several years before Corte Real. As a Venetian himself, Sylvanus may have wanted to leave open the attribution of the land to either Portugal or England, both royal houses.
The final lands in the Americas are the islands of "terra cuba" and "Ispania insu." The latter refers to the island of Hispaniola, which today is comprised of Haiti and the Dominican Republic. "Terra cuba" is, of course, Cuba, which Columbus was convinced was the coast of Asia, as he thought it too long to be merely an island. The use of "terra" instead of insula may imply that Sylvanus agreed with Columbus, or at least that he thought there was more to find in the area. As a whole, the map offers a window into how geographers were reconciling old theories with new information, portraying a Europe looking both east and west.
Sylvanus' world map was included in the 1511 edited edition of Ptolemy's Geographia. Usually placed at the back of this volume, a few copies have also been found in vellum. However, the map was never reprinted, making it rare on the market.
